To all what it may concern; i

e it known that I, ROBERT P. Sco'r'r, citi-.

Zen of the United States, residing at Columr bus, in the county ofFranklin and State of Ohio, have invented certain new andv usefulImprovements in Roadways, of which the following is a specification. Q

The invention relates to pavements or roads and more. particularly tohighways which are paved or formed with a hardlsur face and transverselyarched. 1

.The essential feature of the invention is tolessen the'cost of roadconstruction and make, it possible to provide a road which will resistordinary usage for a longerpek riod, thereby diminishing the cost ofmaintenance, as well as materially reducing the first cost ofconstruction, besides providing a road possessing superior advantages.

The primary object of the invention is to maintain the archor-transverse camber. of

the road without materially increasing the cost of construction orproviding a road which will be expensive in its-upkeep;

'Afurther purpose of the invention isa road which may be cheaplyconstructed, as

it is not essential that the usual curb or concrete, s'tone,' or othertype of foundation be provided to preserve the arch {which is of vitalimportance in the formation ofQa road having facilities for quickdrainage and thereon- The invention consists of a pavement,

highway or roadway generally arched between its sides, restrictionmembers'at the sides of the roadway or pavement having opposed portionsalternately deflected out wardly and inwardly, and cross ties extendingtransversely across the roadway and connecting the" inwardly deflectedportions of the restriction members,

Theinvention further consists of a roadway having the restrictionmembers outwardly curved between their points of connectionby means ofcross tiesto conform to the lateral strain of supporting the arch 4;restriction 'members in sections. er like.

without allowingfor any outwardgive of the restriction "members whichwould tend to allow the arch to settle.

' The invention also consists in forming the Specification of LettersPatent. I, Patented Apr, 11, 1916, "Ap lication filed January 6,1915.Serial mm,

length which are similarlydeflected between their ends and connected bymeans of cross ties. The invention also further consists of restrictlonmembers of equal length having eyes at their ends and arranged ,with theeyes overlapping and cross ties having'their" ends passlng through sucheyes to connect the sections and jointhe' restriction member upon oneside offlthe roadway" with the restriction member upon the opposite sideof the roadway. l I

"I am aware that ed where. crossroads joining curbs or side supports areused, but what I have particu-" larly devised is the curved or archedside supports, which enable me to use a much lighter and more efficientconstruction."

-=It-willbe understoodthat astraight side support would bend or spreadat the middle with very little pressure,and thus let the arch down atthat point. The plan that I use is simply the ordinary bridge engineer--roads have been suggest ing applied to the side strainincident to:weighton the arch tending to flatten the sa me.- 'In a brick road ofordinary construction, the cost may be said to consist ofthree parts.The foundation, the curb and the surfacing. Sometimes these threeelements are; almost equal to each other in V expense.

By reas'on of my invention, the main part of the cost of' the foundationand the curb is dispensed with. That is to say, the iron rods'foutwardly curved at the sides of the road, togetherfwith the cross tierods, take the'place' of the usual stone or cement curb,

sistance is required in the foundation in or- (lento holdup the arch."The arch is supposed to stay in place without anything under: itat all;v I have, however to provide some form upon which to lay the surfacelThis form may' be made more or less firm,

and to such; an improvedzextent thatno as i but mainly to guard againstmoisture with 7 its consequent danger of frost.

The foregoing notes in a generalway some. of. the'lea'ding features ofthe .inventionbut: others will be apparent and suggest theme. selvesasthe nature of the invention is un-.' der's'too'd and to'this endtheinvention may bestated' as-consisting of the novel features,

details ofiiconstruction --.nd"combinatio'n of,

parts which hereafter will be more particularly set forth, claimed andillustrated in the drawings hereto attached in which:

Figure 1 is a top plan view of a roadway embodying the invention. Fig. 2is an enlarged transverse section on the line 2-2 of Fig. 1. Figs. 3 and4 are detail views of bricks, tiles, or like members, forming thesurface of the road.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The invention is adapted for all types of roadways for any purposewhatsoever, the essential feature being the means whereby the sides ofthe roadway are confined so as to maintain the arch.

In accordance with the invention, restriction members 1 are locatedalong opposite sides of the roadway and are connected at predeterminedintervals by means of cross ties 2. The restriction members have opposedportions alternately deflected outwardly, as indicated at 3, andinwardly as designated at L, the cross ties 2 being ar ranged so as toconnect the inwardly deflected portions. In the preferable constructionthe outwardly deflected portions 3 are curved, such arrangement beingfound to give the best results in supporting the arch and preventing anyoutward give in the restriction members which would tend to permit thearch to settle.

The restriction members 3 preferably consist of metal bars or rods, thesame comprising sections of uniform length and provided at their endswith eyes 5 which are arranged to overlap and receive the ends of thecross ties. This arrangement results in a simple construction since thecross ties serve the two-fold purpose of connecting the sections as wellas joining the restriction member upon one side of the road with therestriction member upon the opposite side.

Then the restriction members and cross ties are in position, they occupya position with the cross-ties embedded in the road and with therestriction members sustaining the arch, as indicated most clearly inFig. 2.

For convenience of illustration, the road- Way comprises a surface 6 anda bed 7. The surface 6 may be formed of bricks, tiles, concrete, orother material resulting in the formation of a surface embodying athickness possessing suflicient hardness and rigidity to maintain theoutline or arched form of the road. The bed 7 may consist of earth,sand, concrete or other material. It is not necessary that the bed 7 beformed of concrete, stone, or like foundation usually employed in theconstruction of roadways because the provision of the restrictionmembers and connecting cross ties therefor p'rovides means for holdingthe arch in the required form. As indicated in Fig. 2 the arched outlineor transverse camber of the upper surface of the road is pronounced andsuch arch or transverse convexity is maintained by the means consistingof the elements 1 and 2.

When the surface of the road is formed of bricks, tiles or like pavingor surfacing elements, the same may have their faces straight, asindicated in Fig. '2, or the elements 8 may have their faces oppositelyincline-d so as to interlock when placed together, as indicated in Fig.3. Fig. 4 shows paving or surfacing elements 9 each having a rib 10 uponone face and a groove 11 upon the opposite face so that when theelements are placed together the tongues and grooves match.

lVhen constructing a roadway in accordance with the invention, therestriction members 1 are arranged upon the roadway the requireddistance apart so. that the outwardly deflected portions 3 and theinwardly deflected portions 4 are arranged opposite one another. Thecross-ties 2 are straight and pass through the eyes formed at theoverlapping ends of the sections comprising therestriction members. Theinner faces of the restriction members 1 are straight so as to engagethe hard surface portions of the road and maintain the arch. Thematerial comprising the bed 7 is arranged so as to embed the cross-ties2 and conform at its surface to the outline of the arch or the camber ofthe road in transverse alinement. The paving blocks or other ma terialforming the surface is placed upon the bed 7 with its side portionsabutting against the inner straight faces of the members 1. It is to beunderstood that the outer surface portion of the road may consist of anymaterial which is generally employed to provide a road to resist wear.The crossties 2 and restriction members 1 preferably consist of metal.As shown, each of the cross ties consists of a rod having its endportions threaded, the projecting ends extending beyond the overlappingeyes of the sections comprising the restriction members receiving'nuts12. This construction provides for a limited adjustment of therestriction members should it become necessary at any time to move thesame inward or to admit of such members spreading.

The drawings illustrate an embodiment of the invention but within thescope of the invention as claimed, various changes may be resorted towithout departing from the spirit thereof in adapting the same to meetspecial requirements or conditions.

Having thus described the invention, what is claimed as new is 1. Aroadway providedalong opposite sides with restriction members which haveopposed portions alternately deflected outwardly and inwardly, and crossties connecting the restriction members at points corresponding withtheir inwardly deflected portions.

2. In a roadway, restriction members arranged at opposite sides thereofand comprising opposed outwardly curved portions, and cross tiesconnecting the restriction members at their extremities.

3. In a roadway, restriction members arranged along opposite sides ofthe roadway and of like length and outwardly deflected between theirends, and crossties connecting corresponding extremities of opposedmembers.

4. In a roadway, restriction members arof the roadway and formed ofsections of uniform length, outwardly curved between their ends andformed with terminal eyes, the sections being arranged with the eyesoverlapping, and cross ties connecting the members upon opposite sidesof the roadway and passing through the eyes of the sections and servingas connecting means therefor.

6. A roadway comprising a hard surface portion which is transverselyarched, restriction members arranged along the sides of the roadway andforming abutments for the hard surface arched portion thereof, and crossties connecting the restriction members at intervals, said restrictionmembers being outwardly deflected intermediate adjacent cross ties.

7. A roadway comprising a hard surface portion which is transverselyarched, re-

. striction members arranged along opposite sides of the roadway andforming, abutments for the hard surface arched portion thereof, saidrestriction members comprising sections of uniform length having theirend portions formed with eyes and arranged with the eyes overlapping,and said sections being outwardly curved between their extremities, andcross ties passing through the overlapping eyes and serving to connectthe sections and to join the restriction member upon one side of theroadway with the restriction member at the opposite side of the roadway.

8. A roadway comprising a bed having its surface transversely arched, ahard surface portion placed upon the bed and transversely arched,restriction. members at the sides of the roadway and forming abutmentsfor the hard surface portion thereof, and cross ties embedded in the bedof the roadway and connecting the restriction members at opposite sidesthereof, said restriction members being outwardly curved intermediateadjacent crossties.

9. In a roadway, restriction members arranged along opposite sides ofthe roadway and forming abutments for the surface portion thereof, saidrestriction members having opposed portions outwardly deflected,

cross ties connecting the restriction members intermediate of theiroutwardly deflected portions, such restriction members having: endportions threaded, and nuts mounted upon the threaded ends of the crossties and serving as means for relatively adjusting the distance betweenthe restriction members. a v
